@OP: Did you really stand in abyssea for 60 mins watching someone solo a mob? Really? Really!?! Sweet zombie Jeebus.

If you did, I really have no sympathy. When my ls goes into abyssea with a plan and there's people already fighting the nm we planned on fighting, we go somewhere else. You wasted your own time waiting around for what you probably hoped would be a free nm if the bst died (and let's face it, you probably did think the bst was going to die). If you don't have a plan b or c or q, that's your own fault.
Quite a lot of people make PUG now you know? If you spent an hour forming a PUG and go there you can hardly go do something else, you either wait or disband.
